About the job
We have launched Keet Mobile on iOS and Android, bringing our full P2P technology stack to everyone. Keet Mobile is not your average app: it’s heavy lifting is performed by a custom JS runtime specially designed for peer-to-peer usage (in fact, it reuses 100% of Keet Desktop’s code!). The UI logic, on the other hand, is 100% React Native, giving us flexibility and the ability to iterate quickly.
We believe this pattern opens the door to huge possibilities in the future, and we need your help getting there!
